Creating a main product header with products within?

I have no idea what I’m doing. :pensive_face: I’m trying to get my page up and running. I am trying to figure out how to make different headers such as “Rings” or “Spheres” then add separate items under each header. I see that it asks if I have more in a different size or material but then it doesn’t seem to give me the option of adding photos.

Any help is appreciated.

Thank you.
